Figure 4 Patient Example
Time-strain curves of the 6 left ventricle (LV) segments at the level of the papillary muscles. (A) At baseline, the delay between peak radial strain of the anterior papillary muscle (adjacent to the lateral LV segment; green curve) and the posterior papillary muscle (adjacent to the inferior LV segment; dark blue curve) was 180 ms. (B) After initiation of CRT, the dyssynchrony between the papillary muscles disappeared.
